Tuna and sweetcorn stuffed jackets

This air-fryer frittata uses cooked potato for a fast, golden egg meal.

This recipe makes 4 servings and takes about 12 minutes to prepare plus 18 minutes to cook. Metric and imperial quantities are alternate measurements, so use one system rather than adding both. If you change the yield, keep the pan size and thickness of the food in mind: a crowded pan steams food and a deep baking dish can extend the cooking time.

Equipment

Set out air fryer, 18 cm air-fryer-safe cake tin, mixing bowl, silicone spatula. A wide pan gives moisture somewhere to evaporate; for an oven dish, leave space between pieces so heat can circulate. Use separate board and knife surfaces for raw protein and foods that will be eaten without further cooking.

Ingredients

You will need: cooked potatoes, diced: 450 g (1 lb); large eggs: 6 (6); mature cheddar, grated: 120 g (4¼ oz); spring onions, sliced: 60 g (2 oz); chives, chopped: 10 g (⅓ oz); olive oil: 5 ml (1 tsp). Gather the ingredients before heating the pan so the aromatics do not burn while a measurement is being found.

• cooked potatoes, diced — 450 g / 1 lb
• large eggs — 6 / 6
• mature cheddar, grated — 120 g / 4¼ oz
• spring onions, sliced — 60 g / 2 oz
• chives, chopped — 10 g / ⅓ oz
• olive oil — 5 ml / 1 tsp

Method

Read the full method once, then prepare the ingredients in the order listed. Keep raw and ready-to-eat ingredients separate, and wash hands and equipment after raw-protein contact.

Step 1

Heat the air fryer to 180°C/355°F and brush the tin with olive oil. Spread the cooked potatoes across its base.

Step 2

Beat the eggs with half the cheddar, the spring onions, and half the chives. Pour the mixture over the potatoes and press any exposed potato below the egg.

Step 3

Air-fry for 12 minutes, then scatter over the remaining cheddar. Cook for 4 to 6 minutes more until the cheese bubbles and the centre does not wobble when the tin is nudged.

Step 4

Leave the frittata in the tin for 4 minutes, loosen the edge with a spatula, and finish with the remaining chives before cutting.

Cooking and safety check

The egg mixture must be set throughout; do not serve while the middle is liquid. A time estimate and a browned surface do not prove that the centre is cooked. Use a suitable food thermometer where the ingredient or local guidance requires one, and follow the package or official instructions for the specific food.

Substitutions that respect the dish

A substitution should preserve the recipe’s job, not merely its colour. Use grated Red Leicester in place of cheddar; both contain milk. Leek, softened first, can replace spring onions. Use roasted squash cubes instead of cooked potatoes. A plant-based cheese can replace cheddar, but check its allergen label.

Allergen notes

This recipe contains or may contain milk, egg. Check every packaged ingredient because formulations and cross-contact warnings vary.

Common mistakes and how to correct them

Use one troubleshooting change at a time. If the centre is undercooked, return it to the appropriate heat and check again rather than relying on the outside colour. If the pan is dry, add liquid gradually; if it is watery, reduce uncovered. Texture may also reflect crowded equipment, a different ingredient size, or a changed batch quantity.

• Dice potatoes no larger than 1.5 cm so they warm through.
• If the top darkens early, lower the air fryer to 170°C/340°F.
• Runny egg usually means the tin was too deep; cook in smaller portions next time.

Leftovers and storage

Refrigerate cooled wedges in a sealed container for up to 2 days. Reheat at 160°C/320°F in the air fryer until hot through.

Frequently asked questions

Can raw potatoes be used?

No; cook them first so the egg does not overcook.
